Cobalt(II) porphyrins supported on crosslinked polymer matrix as model compounds

Polymer-bound cobalt(II) porphyrins were studied for their dioxygen-binding capacity. Tetra-aminoporphyrins were anchored on a divinylbenzene (DVB)-cr osslinked chloromethyl polystyrene network. The crosslinked, solid polymers were swelled in chloroform and the swollen polymers were used for the enti re studies. Ortho-, meta- and para-substituted porphyrin systems were devel oped by adjusting the bonding position with the help of suitably substitute d aminoporphyrins. The products were characterized by chemical and spectros copic methods. Cobalt(II) complexes of polymeric porphyrins were synthesize d and characterized by electronic and ESR spectral methods. The spectra gav e evidence for the systematic variation of electronic properties in ortho, meta and para compounds and for the dioxygen-binding capacity of cobalt com plexes. These results are discussed. Copyright (C) 1999 John Wiley & Sons, Ltd.
